GAS-RANGE.

Specification of Letters Patent.

To all whom it may concern: Be it known that we, FRANK A. NUMBER- DING and Earn. V. CoULsToN, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Gas-Ranges, of which the fol- ].owing is a specificatio This invention relates to. gas ranges, and

the invention consists in a range or stove ofa four-hole size in this instance possessing certain novel and original features of construction which relate said holes to each other and to a common exhaust or outlet for the waste products of combustion, thus insuring the healthful and sanitary character of the range in the apartment, all substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of the range with the lids removed and showing the burners. Fig. 2 is a central sectional elevation front to rear, on

. line 22, Fig. 1. Fig. 3 is asectional elevahereinafter more clearly appear. Fig. 4 is a' tion substantially on line 33, Fig. 1, and

designed more especially to show the bottomplate or housing for the burners as will sectional elevation, enlarged, as compared with Fig. 3, of one of the burners and the parts associated therewith. Fig. 5 is a view like Fig. lexcept that the burner is tilted as occurs when it is being removed or replaced. Fig. 6 is a cross section of one of the burners and associated parts and showing particularly its means of support. Fig. 7 is a plan view of one of the burners with its supply pipe and mixer, and Fig. 8 is a side, elevation thereof. Fig. 9 is a bottom view of one of the burner centeringand regulating rings and Fig. 10 is a side elevation thereof.

The range as thus shown belpngs essentially to the class of gas ranges as such in contradistinction to what may be termed a totally different conception from any and Patented Dec. 17, 1912;;

all bf such ranges known to us and apper tains exclusively to a gas range as such and particularly to a style or variety of range which has no oven or other operating features .beneath the top burners shown herein and indicated by b. An oven or other'attachment may be made over the rear of the range, as usually is done, but no part of the present invention being contained in such attachment it is omitted from the drawings.

Now, approaching the details of construction more especially,,we-have, first, the stove orrange top or top plate 2 which covers the entiretop of the range and has a border or flange f about its front and sides and square or rectangular openings or holes corresponding to the four several burners and spaced apart by the cross, bars 4 "and the front to rear, bar 5 of the said top forming parts of the seats for the plates 6 which occupy said holes flush with the top of the stove. The said plates have each a central round hole corresponding to the usual holes in'the tops of stoves for kettles and lids and which receive the lids 7 in this case. One of the front holes is shown as larger in this range than the three others to accommodate what may be termed a double burner I), but all the holes and burners may be alike and no further notice need be taken of this diiference. The several plates 6 are removably seated in the top plate 2 but presumably are not disturbed exce t as it becomes necessary to open the top' 0 the stove more freely to remove a burner or for other unusual reason. Furthermore, the stove is intended to be used withthe lids 7 in place after the manner of a coal stove, so that there is 'no escape of offensive and poisonous fumes into the room as always occurs with the more commonkind of gas ranges which have no exhaust flues and discharge everything directly into the room. The burners b are therefore so located in respect to the openings above and the lids thereon that suitable space is allowed for-the flame beneath said lids, say approximately two inches in a-full sized construction. Each burner is provided with a centerin and airregulating ring 8, which is shape to conform to the outlines of the burner itself in its inner portion and to the collar 10 in its outer portion. The said ring has a flat flange about its top which fits closely at its edge in the surrounding collai 10 and Y which isan integral portion of the bottom plate 12 of the combustion chamber, of which the top plate 2 and the lids and plates thereon form the top or cover and the plate 12 the bottom. The said bottom plate is preferably a cast metal part and unevenly shaped as to its upper surface to get the desired effects or results in combustion and in the exhaust of the foul product-s. Thus, the said late is formed with more or less depression over its entire surface as compared 9 with its straight flat edges which are firmly bolted to the top plate 2 and make a close connection therewith, as seen in Figs. 3 and 4. From the said edges'the plate gradually drops more or less toward its middle on all lines except at its center and rear where an exit 13 is provided 'for the spent gases and something of a trough-like formation leads centrally to said exit from the front to insurea sustained draft which will carry the .said, gases away and supply a suflicient air draft for the burners. However, the lines of depression vary more or less about the respective collars 10, as also seen measurably in Fig. 3, and the said collars rise more or lessabove the bottom plate 12 according to their location front or rear and their relation to the central draft channel. It may be observed here that the portions of these collars which come above the bottom 12 have to do .very materially with equalizing the flame effects of the burners, it being obvious that since the deepest and most direct draft to the exit 13 is along the center front to rear the tendency to draw excessively upon the flame along this line will be correspondingly increased and hence the precaution of providing a .higher flange it toward the center until at the rear they nearly touch I the lid. Precaution must therefore be taken to equalize the flame and avoid unequaldrafts in each .burner individually both downward at front, Fig. 5', and be bodily lifted out by any unskilled person and as easily replaced. A drip pan 20 is fixed-beneath each burner on the stirrup 16' and a drip plate 21 overlies the bottom beneath all theburners and is affixed to the legs 23 at its corners. The said centering rings 8 have inside substantially V-shaped spurs c horizontally disposed and relatively occupying the space between the spurs d of the burner and slightly overlapping the same and apart therefrom relatively as seen in Fig.4, so that a suit-able supplyof air may be provided for the burner from about the outside thereof while there is also a limited opening for air up through its center. Legs or projections 22 are formed on the bottom of the several spurs cof the said rings which,

seat in recesses 24 in the. side of the burner and support the ring apart from the top and outer edge thereof just far enough to permit the'infiow of air to sustain combustion as above described but yet near enough to "avoid the effects of air currents.

Now,.from the foregoing, it will be seen that the only air which is admitted at all into the combustion chamber or space between the closedtop of ,-the range and the bottom plate 12 is such as enters through or immediately about the burners between the centering rispgs 8 and the perforated spurs of the burner burners is safeguarded especially by the collars 10 in such way as to both exclude stray air currents from beneath and to prevent uneven draft from about the tops of the burners. Furthermore, all the foul and unhealthful products of combustion go ofi through the exit 13, and if itshould happen,

as sometimes it does, that a burner is left open more or less without ignition the escaping gas willfpass off into the chimney and not'be discharged into the room.

The-inner edge of the star-shaped 0 ening-in ring 8 follows closely the line 0 gas perforations in the burner b, and as the space between the spurs c'and d is relatively small, only a thin sheet of air is permitted to pass; but, each perforation thereby receives a direct and predetermined supply of air from the outside to promote combustion,

All the air that enters the heating or com bustion chamber housed in by-bottom plate 12 and the cover plate or plates of the stove must pass over and through the burners b,'

which are otherwise openly exposed beneath bottom plate 12.

What we claim is:

1. A gas 7 plates secured together at their edges and the lower plate depressed between its edges to form a chamber and having openings with vertically disposed collars about the same and said collars extending both above and below said plate in varying degrees according to the position they occupy in said chamber, in combination with burners relatively beneath said collars and an outlet for the products of combustion at the rear of the range between said plates.

2. A gas range having a chamber with openings in its bottom and burners therein,

a ring conforming to the shape" of each' range having top and bottom and that the space above the neat-h.

' 3. A gas range having a combustion chamber closed over its top and at its front and sides and having an exhaustopening in its rear and burner openings in its bottom,

A in combination with burnerssup'ported beneath said openings, rings conforming to the shape of said burners and adapted to limit the inflow of air thereto, and collars in said burner openings centering and confining said rings.

4. A gas range havinga combustion charm her with burner openings inits bottom and closed aboutits front and sides to the admission of air,-collars fixed in said openings,

greater de and there y preventing excessive draft in swinging stirrups suspended from said collars and burners supported on said stirrups.

5. A gas range having a combustion chamber with vfipenmgs in its bottom provided with collars, stirrups suspended from said collars and burners-su ported on said stirrups, and air control ing rings supported upon said burners and centered-in the said collars. I

p 6. A gas range having a combustion chamber common to all the burners therein and having a depression centrally .front to rear forming an exhaust channel for the prodnets of combustion, openings in the bottom of sa1d chamber having collars extending abovethe surface thereof and relatively of th as said channel is approached the burnernext to said channel.

7. A gas range having a' chamber .c'losed over its top and having a bottom plate rovided with openings having substantlally band shaped collars about the same, burn ers relatively beneath said collars and means suspending the burners therefrom, and

rings about the upper portions of said bumers supported by said collars and adapted to limit the inflow of air to the burners.

8. A gas range having top and bottom plates closed about their edges and forming a chamber between them, the said chamber having an exit for the products of combustion and the said bottom plate provided with openings for burners and an undulating surface about said burners and inte al collars about said openings projecting 0th above and below said plate, in combination with burners relatively beneath said openings and yokes suspending the burners from sa1d collars.

9. A gas range having independent burners rovided each with a gas suppl pipe at its ont and a mixer on the en' of said pipe, a plate having openings with collars about the same, swinging stlrrups support ars and fixed gas suppl which said mixers are engage In testimony whereof we aflix oursigna tures in presence of two wltnesses.
